Please help me find out the name of this song.

the chourus says:

How does it feel to know that I love you.
I'm lost without you
I can't help myself

Tell me that you love me baby
Tell me that you think I'm sexy

I don't know the rest, if I here it again I'll write more lines.

A guy sings it with a higher tone of voice. I heard it on digital radio so I can't tell who it is.
It's R&B Genree

Please help me out. Thanks
